A crate is pulled up using frictionless pulleys, as shown in the diagram, at an angle of 45 degrees. The masses are, for the small pulley, m₁ 3.70 kg, for the travelling pulley, M₂ 6.70 kg, and for the crate, Mc = 53.7 kg. What is the minimum tension with which the operator must pull, in order to slowly raise the crate? Assume the cable is of neglible mass. m1 Mc M₂ T = =
